Spatial variability of the aspect sensitivity of VHF radar echoes in the troposphere and lower stratosphere during jet stream passages

The aspect sensitivity of SOUSY-VHF-radar oblique-beam echoes from the troposphere and lower stratosphere has been examined for a number of jet stream passages during the years 1990 - 1992.When the core of the jet is overhead or nearly so, vertical profiles of the aspect sensitivity display two notable features.First, the distinction between mainly
